Is she losing weight?? If so I wouldn't wait until October to have her checked out. Doximom11 gave a good differential diagnosis of potential issues.
BTW, cats are different than dogs regarding eating. They can and do cause serious issues by just not eating sufficient amounts. With dogs there is almost always some underlying issues either medical or behavioral with longer term inappetence. Cats can have underlying issues but sometimes can put themselves into liver disease just by not eating.
Lesson: a cat not eating for days should be considered an immediate problem.
